1. Martians invade the East Coast
Orson Welles’s “War of the Worlds” stunt on Mercury Theatre on the Air in 1938 freaked the hell out of a lot of listeners. (Reports by the press of mass hysteria were exaggerated, though.) His tale of aliens landing in New Jersey, broadcast from the CBS studios on Madison Avenue, resulted in listeners suing the station for mental anguish, and 23-year-old Welles thought his career was over. (Spoiler: It wasn’t.)
